Analyses of the Lower San Fernando Dam Failure
The main methods employed for the back analysis of the behaviour of the Lower San Fernando Dam during the 1971 earthquake are described. The requirements for a comprehensive analysis are...
Analysis of Concrete Gravity Dams Using Microcomputers
Monenco Consultants Limited has developed a microcomputer program entitled 'DS2' for the stability analysis of concrete gravity dams. This paper discusses this...
Knowledge-Based Expert System for the Real-Time Operation of Reservoir Systems
An efficient way to avoid the loss of valuable knowledge is to develop an expert system which incorporates hydrologic, hydraulic, system analysis, environmental, economical knowledge based...
Evaluating Uplift Pressures for Concrete Gravity Dams
An approach for evaluating uplift and dam foundation conditions, which resulted from the initial phases of an Electric Power Research Institute (EPRI) study is presented. An earlier study...
Visualization of Flow Phenomena in a Hydraulic Turbine Based on 3D Flow Computations
The fluid flow in a Francis turbine has been analysed theoretically. Advanced techniques have been used for both the flow calculation and the presentation of the results in order to clarify...
Experience with the Application of Fully 3D Potential Flow Analysis to Runner Design
Hydraulic turbines come in various shapes and types depending on their operating conditions. Their performance characteristics depend largely on the runner which is the most difficult...
Guidelines for Failure Investigation
The
Cautious Risk Taking
Traditionally, the design engineer could bear virtually unlimited liability for design failure. Now he is less vulnerable. The concept is less than 20 years old, but since the early 70s,...
Grouting Trends
The grouting industry is discussed and North American practice compared to European practice. There has been more innovation in this field overseas, but there have also been failures....
Specification as a Requirement for Hot Mix Asphalt
A brief description of the current national research programs that affect the development of specifications is included in this paper. Elements of the Strategic Highway Research Program...
Applications of Computer Graphics in Construction
Stone & Webster Engineering Corporation has implemented an integrated computer system for engineering, design, construction planning, and project management based on a relational...
Real-Time Project Tracking
Too often project tracking is based on a job costing program which charges costs to the project based upon invoices from vendors and payrolls of employees. The information obtained from...
Potential Misuse of Construction Scheduling Software
The advent of microcomputers, coupled together with the development of many easy to use and economical scheduling packages, has placed a very powerful tool in the hands of construction...
Real-time Animation of Construction Activities
As a result of 3-D computer modeling, the availability of geometric data in an electronic form makes possible the use of computers for purely construction activities in ways that were...
Effect of Planning Errors on Construction Safety
A discussion of the planning phase of the building process associated with all the activities that are accomplished during this phase is presented. The different types of errors that occur...
Visual Scheduling
This paper presents a look at new innovative way to provide project schedule. The primary target is in visual scheduling presentation techniques. The systems presented include a system...
Eliminating Bias in Construction Schedules to Measure Time
Schedules developed for use in managing the construction process which are accurate for that use are not necessarily sufficiently accurate to measure and evaluate delays and changes to...
Project Control Via Acoustical Sensing
This paper describes ongoing research into automating the process of collecting project control information using acoustical sensing devices. The paper describes how frequency spectra...
Decision Support System for Achieving and Measuring Design Effectiveness
A microcomputer program is developed to serve as a decision system for improving design effectiveness. The program, called 'Design Effectiveness Evaluation and Implementation...
Pumped-Storage: An Analysis of Optimal Capacity
This paper presents a systems analysis procedure to evaluate planning alternatives for pumped-storage operated in an existing power system. This procedure can be used by planners and engineers...
